Article Overview
This CPT Assistant article explains how to distinguish conversion and revision hip arthroplasty scenarios and why that distinction matters for reporting. It is aimed at coders, billers, and clinicians who work with orthopedic operative documentation, especially cases involving prior hip surgery, staged procedures, and postoperative modifier use. The article presents general guidance through a coding brief, a conversion-versus-revision discussion, and several FAQs that address common hip arthroplasty situations.
